Page 4: Description
Overview Description The MCHXXX Single Axis Control Handle provides remote electrical actuation of Danfoss pumps/motors, and or other electrically-actuated pump strokers for open loop control systems. The MCHXXX can function as a setpoint for analog or microprocessor-controlled systems for controlling position, speed, pressure, horsepower or other dynamic parameters. -

Technical Information MCHXXX Installation For optional connectors, contact your Danfoss representative. Wiring A barrier terminal strip inside the handle’s case provides connections to power, ground, and potentiometers when no external cable is ordered. Run a cable from the strip through the strain relief provided on the side or bottom of the case. - Page 12 Clockwise increases output L with (2) threshold adjustments Forward threshold Counter clockwise increases output Reverse threshold Clockwise increases output Forward full stroke Clockwise increases output Reverse full stroke Clockwise increases output 11022667 | BC00000033en-US0601 12 | © Danfoss | February 2017...

Page 14: Connection Diagrams
MCHXXX potentiometer models having either two or single 200 Ohm pots are configured to directly control Danfoss variable pumps with electrical displacement controls (EDCs). Whether two or single pots, both require the same electrical connection to the EDC and only one of the dual coils needs to be connected to achieve forward and reverse pump flow. -
